I have ubuntu 11.10 installed on my system, upgraded from 11.04. I need to install the elok touch screen driver. as this driver only supports kernel 2.6 and not 3, I switched to kernel 2.6 in boot loader. now that I want to make the elok.so module, it gives me an error
make
make -C /lib/modules/2.6.38-8-generic/build SUBDIRS=/etc/opt/elo-ser/elok_s-source modules
make: *** /lib/modules/2.6.38-8-generic/build: No such file or directory. Stop.
make: *** [default] Error 2
this error is becuase, when I upgraded from kernel 2.6 to kernel 3.0, kernel 2.6 was removed from /usr/src and in the /lib/modules/2.6.x.x there is no build directory.
I do not know how to solve this problem, please note the details of everything i should do to run my module.
